python - django modelformset_factory POST request data retrieval -

i got django 1.9 , found out modelformset_factory useful can setup forms without major afford.

now came realise upon submitting form (post method)i need figure out objects have added , removed .

this view got :

def def_accounts(request):      list_services_list()     services_list_topicformset = modelformset_factory(services_list, form=services_list_nameform, fields=('accounts',), can_delete=true)     items = services_list.objects.all()     formset = services_list_topicformset(queryset = items)     if request.method == 'post':         t_formset = services_list_topicformset(request.post)         if t_formset.is_valid():             t_formset.save() 

i have looked post request , seems full data submission, seems doing full object refresh cannot distinguish post action in there..

any on this?

thanks!

edit seems can figure object being added toe form follows:

    if t_formset.is_valid():         instances = t_formset.save()         instance in instances:              print "instance.id: " + str(instance.id)              print "instance.accounts: " + str(instance.accounts)              instance.save() 

output:

> instance.id: 21 > instance.accounts: test1 

still trying figure out how can objects being deleted!

any idea?

thanks!

when save model formset calling formset.save(), 3 attributes formset.changed_objects, formset_deleted_objects , formset.new_objects store changed, deleted , new objects respectively.

therefore, can access deleted objects formset.deleted_objects.
